,FEED-WATER PURIFIER AND HEATER.

SPECIFICATION forming part of Letters Patent No. 346,247, dated July 27, 1886.

(No model.)

To all whom t may concern:

Be it known that I, JOHN P. WARNER, a citizen of the United States, residing at Philadelphia, in` the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Feed-Water Heaters and Purifiers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled the art to which'it ap pertains to make and use the same.

lWIy invention relates to heaters and purifiers of feed-water for boilers; and the object is to improve the construction of the heater and purifier patented to me the 21st day of July, 1885, and numbered 322,767; also, to produce a means by which the water coming from the pump can be heated before entering the puriiier; also, to provide a removable casing, to be applied to the main purifier at will, and containing within such casing a coil by which the water from the pump is heated; also, to arrange a means by which the exhaust-steam used for heating the coil containing the pumpwater, can be employed for heating a building, or can be carried into the upper part of the purifier to be condensed and utilized with the feed-water.

The invention consists in the construction of certain parts and arrangement of details, as Will be more fully described hereinafter, reference being had to the accompanying drawings, and the letters of reference marked thereon.

The same letters indicate similar parts in the figures of the drawings, in which- Figure 1 represents a verticall section of my improved heater and purifier, and its casing and coil. Fig. 2 is ahorizontal section on line x of Fig. 1.

In the accompanying drawings, a vessel of suitable dimensions and material is represent` ed, according to the size of the boiler, to which it is connected by the steam and water pipes hereinafter referred to. This vessel, as in my former patent, consists of the main part A, having the anges c and a', to which the steamdrum B is bolted at the upper end, and the mud-drum O to the lower part by suitable bolts, and between the flanges is preferably placed my packing to form steam-tight joints. The steam-drum is provided with the diaphragm b, and in this is secured the checkvalve c, and the interior pipe, G, is secured at the upper end. To this pipe, the pipef is attached and extends to near the bottom of part A, and around the pipe f are arranged the perforated diapliragms or screens H, while the interior of said pipe fis provided with the perforated diaphragms f. Into the upper 50 part of the steam-drum B is extended thejetnozzle D, connected by a branch pipe, d, with the steam-pipe E, communicating with the steam-space in the boiler. The blow-off' pipe K is connected with the mud-drum, and in the branch pipe d and said blow-off pipe K are arranged the valves 7c, connected by the rod L to operate said valves. Between the diaphragms H is arranged a quantity of fine Wiregauze, preferably in sheets, or some other iiltering material. The feed-pipe I communicates with the boiler, and conveys the purified water to it. All these parts are of similar construction and operation as those in my former patent, and are therefore not described 7 5 more definitely.

The main part of my present invention is constructed as follows: A casing, M, of proper dimensions, is placed around the shell A, and in it is arranged a coil, N, which communicates at its lower end with the feed-pump or other source of' supply and at its upper end with the upper part of the steam-drum. The lower fiange, a', of the shell A is extended circumferentially, and forms a bell-mouth to receive lead or other suitable packing when the cylinder r is inserted therein. The upper part, N, of the casing forms a head, and receives at its outer end thelupper end of said cylinder with a packing, and its inner end embraces 9o the shell, having also a recess, a, for receiving a suitable packing, so as to form a steam-tight joint. This entire casing can be easily removed by the removal of the bolts c, which hold it in place. The exhaust-pipe O enters the casing at its lower end and passes out at itsA upper end, and the exhaust-steam may be con` veyed either into suitable pipes to heat the building, or it may be conducted into the upper part of the steam-drum tobe condensed, and to assistin heating the feed-water, as shown in dotted lines in Fig. 1. The coil N communicates with the upper part of the steamdruni B, and the water therein contained having been properly heated enters into the steamdrum and passes through the inner pipe, up through the diaphragms H and filtering material, out through they pipe I into the boiler in a purified and heated state. This casing can be very easily and readily applied to old as well as new heaters and purifiers, with its coil, at a very small expense, and will be found to be of great advantage, as the feed-water will enter the boiler Vat a much higher degree of heat than When the purifier is usedwithout it. Furthermore, the puried water passing' up through the diaphragms and filtering material will receive-an additional amount of heat from the exhaust-steam coming in contact with the shell A. It will be seen that it is also of great advantage to utilize the exhaust-steam, first, to heat the water in the coil N, and then either for heating the building or condensing it and using it with the feed-water. A suitable dripcock, p, in the bottom of the casing serves to withdraw any condensed water that may have accumulated in the casing.

The operation of the apparatus will be readily understood by those skilled in the art, and will require no further elucidation here.

I aware that coils arranged in a casing and Having thus described my invention, what I claim isi f 1. The combination of a heater provided with steam-jet D', interior pipe, G f, steamdrum B, and muddrum C, and the diaphragme H, for supporting the filtering material, with the removable casing M and coil N, al1 arranged and adapted for operation as shown and specified.

`2. The feed-water heater herein described, consisting of a shell, A, steam-drum B, partition b, steamjet D, interior pipe,G f, dia phragms H,and filtering material, in combination with a' coil, N, and removable casing M, and the pipes with their connections, all yconstructed and arranged as shown and specified.

3. The combination of a feed-water heater, constructed as shown, with a removable casing, M, supported at its lower end on an extended flange, a, and connected at its upper end to the heater by a bell-mouth head, N, having a packing-joint at both ends, and applied as shown and specified. v

In testimony whereof I hereby aix my signature in presence of two witnesses.

JOHN P. WARNER.
